MAN UAI MOTOR.

SPECIFICATION forming part of Letters Patent No. 452,085, dated May 12, 1891.

Serial No. 348,789. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL R. SHEEN, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented a new and useful Manual Motor, of which the following is a specification.

My invention is in that class of manual motors in which power applied to a lever is made through the agency of suitable pawls and ratchet-wheels to rotate a shaft; and it relates, first, to means for utilizing as much as possible of the force applied, and, second, to means whereby the lever can be made to give the shaft a rotation in either direction and at different speeds.

In the drawings forming part of this specification, Figure 1 is a perspective view of the complete machine. Figs. 2 and 3 are detail views.

The shaft E, which it is desired to put in motion, has rigidly mounted upon it at short distances apart three ratchet-wheels C 0' C The outermost ratchet-wheels are of the same size, but have their teeth reversed, while the central ratchet-wheel C is of a smaller diameter than its fellows.

To .one side of the shaft E, but parallel thereto, is a fixed rod F. Upon this rod, and free to move thereon, are two levers A A, so connected as to be free to oscillate'independently, but to move together longitudinally, on the rod.

Pivoted to the lever A are two toothed pawls D D, resting upon opposite sides of the ratchet wheel 0 and having their teeth adapted to engage those with which they are in contact. By this means both up and down movements of the lever will actuate the ratchet-wheel O and shaft E. On the opposite side of the lever A are two similar toothed pawls D D, havingtheir teeth adapted to engage the ratchet-wheel 0 when the lever A has been shifted on the rod F.

The lever A is provided with two similar pairs of toothed pawls D D to engage with the same ratchet-wheels.

At a suitable distance below the lever Ais a platform B, supported upon springs I, and in the upper face of this platform are three grooves J, each in the same vertical plane with one of the ratchet-wheels 0. These grooves are adapted to receive the lever A and are provided with buttons J for retaining the lever therein.

By means of cords H, attached to the pawls D D, and passing from thence through eyes G to the extremity of the lever A, said pawls can be Withdrawn from engagement with the ratchet-wheels whenever so desired.

Adj usting-cords H, fastened to the fulcrum ends of the levers A A and passing through eyes at the ends of the rod F, and thence through eyes on the lever A to the handle of the same, enable the levers to be shifted to engage a new ratchet-wheel after having first raised the lever A from its groove J.

In using-this manual motor the operator stands upon the platform B and manipulates the lever A. When bearing down upon the lever A, the platform is relieved of a portion of his weight, and accordingly rises, and, vice versa, when raising the lever the platform is depressed. The platform being connected with the lever A, there is obtained as a resultant action upon the shaft E the sum of the movements imparted to the levers A and A.

By means of my triple arrangement of ratchet-wheels and of their actuating mechanism I am enabled to communicate to the shaft E either a forward or backward rotationror one of .different speed.

What I claim as my invention, and desire to secure by Letters Patent, is as follows, to wit:

1. The combination, with a revoluble shaft having a ratchet-wheel fixed thereon, of two levers having pawls engaging said wheel, and a spring-supported platform connected with one of said levers, substantially as and for the purpose specified.

2. The combination, with the shaft E, having the dissimilar ratchet- Wheels 0 C C mounted thereon, of the fixed rod F, parallel to said shaft, and the lever A, loosely pivoted on said rod and provided with pawls D D,whereby the lever can be adapted for actuating the shaft dissimilarly, as set forth.

3. The combination, with the shaft E, having the dissimilar ratchet-Wheels C C C fixed Wheels, levers, and pawls, of the eyes G and thereon, of the movable levers A A, having cords H, as and for the purpose specified. a common fuleru In and suitable pawls, and the Spring-supported platform B, having grooves 5 J and buttons J, as and for the purpose set Vituesses:
